WINDOW-SAGE '.FASTENER.'

Improvements in l/Vindow-Sash Fasteners.,A

of 'which the following is a specification.

Myinvention relates to improvements in window sashadjusting Vand locking mecha nism; One of itsobjects isftoprovide forl adjusting the lower or upper or both sashes to relatively different positions in-v the. window frame. Another Objectis tofprovide for securely locking either ofthe sashes 1n k,closed or partly open position', .so aslnot to be liable to be opened from the exterior. .A nother object-is to` provide for, temporarily throwing the sash lockinggmeans out of op-'Ky erationuntil again requiredfor use. 'My

invention also comprises cert-ain details of form, combination, and' arrangement. all which will be fully set forth in the description of the accompanying drawings which:

Fig. 1 is a plan of a window frameand sashes with my improved locking and adj usting'means applied thereto,

Fig. 2 is an enlarged plan of one of the locking members.

Fig. 3 is a view similar to F 2 showing a different positionl of the operative parts.

Fig. 4l is a section taken on line fie- 4; of Fig. 2.

Fig. 5 is a sect-ion taken on line of Fig. 3. Y

Fig. 6 is a plan view of one of the window frame engaging members detached.

Fig. 7 is a view similar to Fig. 6 illustrating` a modification.

Fig. 8 is a'perspective view of a rack to be employed with'the locking member of Fig. 7.

rEhe accompanying drawings illustrate the preferred embodiments of my invention, in which 14; represents the window frame, 15 the lower sash and 16 the upper sash. The sashes may be counterbalanced by means of Weights and cords, or not, since my locking' means may be employed to advantage in either event.

My improved adjusting and locking means is adapted to be applied to the upright kstile of the sash at either the right hand side or the left hand side, as may be preferred, by inverting the locking member. The locking and adjusting` apparatus comprises a frame 17 having screw eyes 18 to Specification of Lettersglvatent Patented Feb. 21', 1922.'

i enable it to be, firmlyattachedtoI the up-KVLV rightl` stile .'19 lof the sash,preferably near the .center of rsaid stile, so that a person from the exterior of the window.v would find it ydiiiicult to reach inl and release the sash locln/in the event that the@ window was 'partlybperr The framev 17 has arecess 20 lin which are locatedIengag'ingorlockingk members 21 and 22, saidv locking members being pivotally supportedupon the journal rods 24 and 25, )referably rigidly connected at opposite ends tothe frame 17 and serving to strengthen the frame and yto firmly lock the membersy 21 and 22 in position relative to the frame.

The members 2l and 22 are preferably of stamped sheet metal in order to avoid liability of breakage, and also to insure suf-f icient accuracyl to render'fsaid members practically interchangeable.. yThe main Yportion of themembers 21 and'22, which are counterparts one of the other, are yof irregulary curved or cam shaped ontline,`journaled eccentrically, and having recesses therein tov serve as housing spacesk for their respective actuating springs. VThe outer engagingv j faces'of said members 2 1and 22 are preferably 'for ordinary purposes plain curved faces presenting suflicient surface in engage- Vment with the window frame so as to firmlyv hold the sash in position against displacement withoutlliability of injuring or marring the window frame. Recesses 26 are cut out to enable one end ofthe actuating 21 and 22 into engagement with the frame 17, or a stationary part carried thereby. The members 21 and 22 are also yprovided with actuating handles, 27 and 28, preferably formed integral by stamping. The actuating springs 29 are coiled about the journal rods 24 and 25 with one end seated in a perforation 30 in the member 21 or 22, While the opposite end of the spring passes through the recess 26 toengage a rod or stud 31 carried by the frame 17 thereby throwing the tension of the springs 29 upon the locking members 21 and 22 to cause the cam or eccentric faces of the members 21 and 22 to move toward each other as indicated by the arrows in Figs. 1 and 2,7and to therebyengage the face Vof the facing strip 32 of the window frame opposite the lower sash, or a separating strip 38 interposed between the two sashes and in position to be en ged by the locking members 21 and 22 of the upper sash. With the cam faces of the locking members 21 and 22 in engagementvvith the Window `frame, any pressure exerted toforce one of the sashes upwardly .will tend to the locking of a member 21 more irmly with` the window frame, while any. pressure down-`4 wardly on either sash will tend to cause a lockin member 22 Yto engage more Ii'rmly with t e Window frame, Vand thus effectively lock the. sashes against movement in either operated' or'released by a person from the exterior.

It is sometimes desirable to lock the members 21 and 22 out of engagement with the Window frame on one or both sashes temporarily, and in order to do so I provide a leaf springvmember 34 having latch members 35 to respectively engage the handle's27 and 28 of the members 21 and 22 and to lock them in substantially the position shown in Fig.` 3 out of operative relation to the Win# dow frame, until it is desiredto release them,

when pressure is applied to the head or push-button 37 to depress the latch members" and release them and 28.Y

- For use on car Windows, and for similar from the handles 27 purposes Where the Windows are subjectedv to considerablevibration, I preferably Vmill The locking members are also orvrib the engaging faces of the members 21 and 22 as illustrated at 21 in Fig. 7, and provide'i connection therewith rack members '36 of metal to be applied to and attached tothe Window frame in position to beengaged `by the ribbed faces ofthelockincr members.r

2The' apparatus herein illustrated and described is capable ofrconsiderable modification Without departing from the principle of my invention,

lVhat I claim is: n 1. A sash fastener comprisin a frame, a pair of spring actuated astenlngmembers eccentrically pivoted on said frame, each member having a handle extension, and a vspring latch mounted on the frame between said handles and having apair of projections each ofwhich is engageable With one 0f thehandles to hold the astening members in released position.

2. A sash fastener comprising aV frame, al

pair of fastening members mounted in said frame, each member comprisinV a cupped sheet metalv head having a hand e extension, an eccentric pivot pin extendino' from the frame through said head, an a spring coiled around said pinand housed in said head and connected thereto atone end, the flange `of the cupped head havin a recess through which the4 other end of t e spring projects to contactl with the frame.

In testimony whereof I have affixed my signature. Y
